Proteins are made up of amino acids and can form a variety of substances in the body. These include enzymes that catalyze biochemical reactions, antibodies that help fight infections, hormones that regulate physiological processes, and structural components like collagen in connective tissues and keratin in hair and nails. Additionally, muscle tissue itself is primarily composed of proteins, which play a crucial role in movement and support.
